Yes / No – A Minimal Habit Tracker Did you do it today — or not? Yes / No is a radically simple habit tracker designed for people who feel overwhelmed by traditional habit apps. No streaks, no charts, no badges, no social pressure. Just a clear question and a single tap. Each day, you answer one thing for each habit: Yes or No. That’s it. Why Yes / No? Most habit trackers try to motivate you with numbers, achievements, and endless analytics. Yes / No does the opposite. It removes everything that creates anxiety or friction and leaves only what matters: recording reality. Features • One-tap daily tracking: Yes or No • Support for multiple habits (up to 5) • Clean, distraction-free interface • Simple calendar view with color blocks • Edit past days anytime • Optional daily reminder • All data stored locally on your device • No account. No ads. No tracking. Designed for calm Yes / No doesn’t try to push you. It doesn’t judge you. It simply remembers what you did. If you want a habit tracker that stays out of your way, this is it.
